	What is Phonology Assistant
Phonology Assistant is a computer program to assist users in phonetics and phonology. It creates consonant and vowel inventory charts from a data corpus and allows a user to search that corpus for phonetic patterns within specified environments.
	Minimum System requirements
•	Computer and processor: Computer with Pentium (or equivalent) at:
•	333 megahertz (MHz) or higher if Phonology Assistant doesn’t need to read data from a FieldWorks database.
•	1 gigahertz (GHz) or higher if Phonology Assistant needs to read data from a FieldWorks database.
•	Memory: 128 MB of RAM if Phonology Assistant doesn’t need to read data from a FieldWorks database. Otherwise, 512 MB of RAM is required.
•	Hard disk: Hard disk space requirements will vary depending on existing machine configuration. If the Microsoft .Net Framework 2.0 is not installed, then 284 megabytes is required for installation. Otherwise 13 megabytes is required.
•	Operating system: Windows 2000 with at least Service Pack 4 (SP4); or Windows XP with Service Pack 2 (SP2), Windows XP Media Center Edition, or Windows Vista.
•	Display: 1024 by 768 pixels screen resolution (for laptops, use native display resolution).
•	Peripherals: Mouse or compatible pointing device.
Note: The more RAM and the faster the CPU, the better the software will perform.
	Upgrading related software
If you are using Phonology Assistant, FieldWorks, Speech Analyzer, and/or SIL Converters, you should upgrade them all to avoid eventual conflicts with older versions of the others. If you no longer need one of these products, first remove it, then upgrade to at least FW 5.0, SA 3.0.1, and/or SIL Converters 2.6.1. The new software is available on the SIL Language Freeware CDs or may be downloaded from:
  FieldWorks 5.0: http://www.sil.org/computing/fieldworks
  Speech Analyzer 3.0.1: http://www.sil.org/computing/sa/
  SIL Converters 2.6.1: http://scripts.sil.org/EncCnvtrs
	Upgrading from Phonology Assistant 2.x
Phonology Assistant 3.0.1 does not offer an automatic upgrade path from Phonology Assistant 2.x databases. The best way to make use of data from a Phonology Assistant 2.x database in Phonology Assistant 3.0.1 is to export the data from the Phonology Assistant 2.x database into a standard format file, convert the data to Unicode, and use the resulting file as an SFM data source in a Phonology Assistant 3.0.1 project.
The installer for Phonology Assistant 3.0.1 will not remove an existing (older) version of Phonology Assistant or Speech Tools. Phonology Assistant 2.x and Phonology Assistant 3.0.1 may coexist on the same computer without conflict. When you no longer need the older version, remove it by using the Windows Control Panel. 
Note: previous versions of Phonology Assistant have been bundled in the Speech Tools package. Removing Speech Tools also removes any other currently installed Speech Tools applications including Speech Analyzer 2.x and IPA Help 2.04.
	Upgrading from Test Versions of Phonology Assistant 3.0
Phonology Assistant 3.0 was released to a limited number of test users and only exists as a test version. Version 3.0.1 is the final, corporate release of version 3.0, the only difference being some bug fixes. Before installing version 3.0.1, you must uninstall version 3.0.
	For users of beta versions before 13-Feb-2007
If you have used test versions of Phonology Assistant 3.0, be aware that opening projects created with test versions dated before Feb. 13, 2007 will cause the loss of the project’s ambiguous sequences. Therefore, if you are running a 3.0 test version dated before 13-Feb-2007, it is recommended that you run that version, open all your Phonology Assistant projects, and note their ambiguous sequences. Then uninstall version 3.0 and install 3.0.1. Then, open your projects using version 3.0.1 and reenter those ambiguous sequences in their appropriate projects.
	For users of beta versions before 3-Aug-2007
If you have Phonology Assistant projects created using a 3.0 test version before Aug. 3, 2007, you will need to delete the project’s field information file before opening the projects using version 3.0.1. The field information file is saved in the same folder as the project file (.pap file) and is given a name in the format x.FieldInfo.xml where ‘x’ is the name of the project. If the project contained custom fields, you must re-add them after deleting the field information file and opening the project using Phonology Assistant 3.0.1.
If projects created before Aug. 3, 2007 contain FieldWorks data sources, after opening the project in Phonology Assistant 3.0.1, click the File menu and choose Project Settings. Remove all FieldWorks projects from the Data Sources list and then add them back again, making sure to specify their properties on the FieldWorks Data Source Properties dialog box.
What to expect during installation
•	The process of installing Phonology Assistant is automated from start to finish.
•	The Master Installer controls the installation sequence. It is the setup.exe program in the root directory of the installation CD or web download. If you are installing with an installation CD, the Master Installer will auto-run when the CD is inserted into the drive. The Master Installer often displays a status window toward the lower left of the screen.
•	Phonology Assistant depends on some other software products to be present on your computer in order to run. If the Master Installer detects that you do not have them, it notifies you, and then installs them. Additional dialog boxes might appear for individual software product installers.
•	In some circumstances, the computer must restart (reboot) after installing an individual software product, but before the entire installation sequence is complete. Allow the computer to restart. If you are installing from a CD, do not remove the CD from the drive.
•	At the end of the entire installation sequence, a completion message appears. Do not assume the installation has finished until the completion message appears, even if the Phonology Assistant application shortcut appears on the desktop.
•	If you need to cancel the installation sequence, do one of the following:
•	If an individual product installer dialog box appears, click Cancel.
•	Otherwise, click Cancel on the Master Installer window. The Master Installer cannot stop an individual product installer, but it can prevent other installers from starting.
	Installation issues
•	If the Master Installer fails to start after the computer restarts, and the completion message does not appear, restart the Master Installer. It is the setup.exe program in the root directory of the installation CD or web download. It continues the installation sequence where it left off before the computer restarted.
